DUMPING-WAGON.

vide in a dumping wagon means for auto" matically removing the end ortail-board as the wagon is dumped. I

A. still further object of the invention is to )rovide a gearingmechanism associated Wit the wagon body .nd with the frame or runninggear, which maybe operated in one direction for moving the Wagon body toa dumping position and operated in an opposite direction for moving thewagon from a substantially dumped position back to its original positionon the frame or running gear.

ln carrying out the objects of the invention, a running gear is providedformed with a supporting frame. On this supporting frame is arranged aplurality of rollers q designed to support a body which may be "dumped.This body is adapted to be actualt) b ll

ated by a rack pivotally connected therewitln which in turn is moved bysuitable gearing, the gearing being arranged with crank engaging memberswhich when oper-. ated in opposite directions will move the rack andwagon body in opposite directions, namely, to a dumped position and fromthe dumped position to the original working position. Connected" with.the wagon body and the frame is an arrangement of levers connected withthe tailboard of the wagon body so as to automatically raise thetail-board simultaneously with the dumping ofthe body.

A practical embodiment of the invention is represented in theaccompanying drawings forming apart of this specification, in whiol'isimilar characters of reference indicate eerresponding parts in all theviews.

Figure 1 is ,a side view of an embodiment ofthe invention; Fig. 2 is aside view on an erllarged scale of a wagon embodying the iHLVQDtlOII;Fig. 3 is a top plan view Specification of Letters Patent. Patentedllllalr. Sil lll'l lllillt I Apprtcation filed may 10, 1913. Serial No.766,747.

of the wagon frame and running gear shown in Fig. 2; Fig. l is a sideview of the structure shown in Fig. 3, the rear axle and bracing linksbeing removed; Fig. 5 is an enlarged detail fragmentary sectional viewdisclosing the body moving rack and the gearing therefor; and Fig. 6 isan enlarged detail fragmentary side view of one of the rear supportingsprings and the links associated therewith and with the rear axle.

Referring to the accompanying drawings by numerals, 1 indicates anautomobile structure provided with suitable steering apparatus, engines,and the like. lhe engine and driving mechanism of the auto mobilestructure is designed to drive one or more chains 2 which engagesuitable sprockets 3 arranged on the front axle a of the dumping wagon5. The traction wheels mounted on axle 4 are connected therewith so asto act as drivers in the usual manner. In order to provide a propersteering of the device, axle l is designed to co act with a suitableturntable or fifth wheel 6, supporting the front part of the dumpingwagon. The rear axle 7 of the dumping wagon 5 is provided with any kindof traction wheels 8. Mounted on the turntable 6 are a plurality oflongitudinally arranged beams 9 which, together with the front beam 9and any desired number of auxiliary cross beams, forms a frame. The rearend of each of the beams 9 carries a .bracket 10 (Fig. 6) whichaccommodates pins 11 and 12. The pins 11 and 12 act as journal pins forlinks 13' and 14:, which in turn are pivotally connected by pins 15 and16 with a suitable clamp 17 held in placed by bolts, or otherwise onaxle 7. The clamp 17 is formed with squared portions to properly fit thesquared shaft 7, but it will be perfectly evident that if shaft 7 was ofany shape the clamp could be made of a corresponding shape. A spring 18has one end arranged to pivotally engage the journal pin 12 on bracket10, while the opposite end loosely presses against axle 7. The center ofthe spring is clamped to the beam 9 by suitable substantially U-shapedclamps 19 and cross bars 20. Nuts of any desired kind are provided formembers 19-so as to firmly clamp bars 20 against the spring whichpresses against the filling block 21., and block 21 in turn restsagainst plate :22 which carries the brackets 10. Plate 22 is connectedin any desired way with the merely .,'is a load thereon, a rack i adumped full lines and ,31, shown. in Fig 3,

beam 9. In this way a resilient support is provided for the rear of thewagon 5, while any usuai'or preferred form of spring may be with theturntable 6 at the forward part of the wagon. The arrangement of thelinks 13 and 14: co-acts with the brackets '10 and clamp 17 and with thespring, so that when the rear of the wagon is moved up and down, theaxle 7 will be normally held in proper p osition and prevented fromturning.

. Arranged on each of the beams 9 are a plurality of brackets 23carrying rollers 24 which act as antifriction supporting means for "thebody supporting beams 25 forming part of ihe body 26. The bodysupporting means are designed to freely slide to the rear and thus allowthe wagon to) dump, as shown in Fig. 2, whenever desired. Rigidlyconnected with the two side beams 25 are-stops or hook members 27,designed engage projections 28 and 29 arrangedfiii the beams 9. Theprojections 28 and 29 are the ends of bar 30 extending beyond the sidebeams 9, as clearly shown in Fig. 3. If desired, a central hook, or anumber of central hooks, could be used without departing from the spiritof the invention, as; the same easily operaie and correctly engage thebar 30. In order chat the body 26 may be moved back and. forth asdesired even when there i 31* is pivoted at 32 to a suitable bracketvmounted on the body 26. Freferably fihere are two of these racks soas'to cause a more even movement of the body 26. The racks 31 aredesigned to engage a pinion 34 rigidly secured to shaft Theshaft 35 hasalso rigidly secured thereto gears 36 near each end designed to meshwith gears 37 ed 39 and 4c, respectively.

The g. o: and are rigidly secured to the Sb? 1, while gears 88 and 46are rigidly secured to shaft 452. Shafts 41 and 4:2

extend beyond the outside beam 9 on each side of the wagon so as toreceive clutch heads The clutch head 43 on shaft 42 is designed torotate shaft 42 in one direction when a crank 44 is applied thereto soas to cause the body 26 to move back from position to a position shownin in Fig. 2; en it is ,esired to cause the body 26 to dump, crank 44 ismoved over to either of the clutch heads 43 on shaft 41 and rotated,After the wagon b0 26 has been moved back to its working position, asshown in Fig. 2, a. locking pin 45 may be used and may be passed througha projection 46 at the forward end of the body 26 and through a suitablebracket l7 (Fig. 2). In addition to these securing means suitable books48 may be used. The

Chocks 48 are pivot-ally connected with any part of the running gear, asfor instance cross beam 9', and are designed to engage suitable pinsarranged on the wagon body 26. In moving the wagon body 5 from thedumped position back to the working positioIu-blie forward end isdesigned to be stopped by the cross beam 10 and also by suitable stops49 associated with the cross beam 10.

In order that the end board or tail-board shall automatically open or beremoved, the same is pivotally connected at 51 to an arm 52 on each sideof the wagon. The arms 52 are pivotally connected at 53 to the wagon andhave pivotally connected intermediate their length links 54. Pivotallyconnected with the links 54 are connecting rods 55, in turn pivotallyconnected at 56 to the outside beams 9. In order to hold the tail-boardproperly in position at the lower end, a book 57 may be used which, orcourse, is to be unfastened previous to the dumping of the Wagon. As thebody 26 moves to the rear the links 54 and rod gradually assume theposition shown in dotted linesin Fig. 2, but do not act upon thetail-board 50 until they have formed a straight line, whereupon theywill prevent any further bodily rearward movement of the arms 52 thatwill holdthe upper part against further moi ement, and as the lower partcontinues to move that the tail-board will be raised as shown in dottedlines in Fig. 2. In order that this action may be carried out withoutundue friction, anti-friction rollers 58 may be arranged at the rear ofthe wagon body 26 for guiding the tail-board 50 in its movement. Whenthe wagon body 26 is moved back to its original position the tail-boardwill automatically move to its correct position so that the book 57 maybe again placed in position manually.

Having thus described my invention I claim as new and desire to secureby Letters Patent In a dumping wagon of the class described, a runninggear provided with a supporting frame, a body adapted to be dumpedtherefrom, said body being formed with a tail board, a pair of armspivotally connected at one end with said body and at the other end withthe upper ed e of said tail board, means for locking the lower end ofsaid tail board in place while said body is on said frame, a linkpivotally connected to each of said arms substantially central thereofand extending normal thereto when the body is on said frame, a rodpivotally connected and to said supporting frame, said rods beingconnected with said supporting frame in front of said arms, whereby whensaid body is dumped the tail board and the upper end of said arms willmove therewith until said links and said rods move to a the result willbe.
